Eighteen-year-old Tsukasa Mizugaki has failed his college entrance exams, but after pulling some strings, he manages to land a job at the Sion Artificial Intelligence Corporation. SAI Corp is responsible for the creation of Giftias—highly advanced androids which are almost indiscernible from normal humans. However, unlike humans, Giftias have a maximum lifespan of 81,920 hours, or around nine years and four months. Terminal Service One, the station Tsukasa was assigned to, is responsible for collecting Giftias that have met their expiration date, before they lose their memories and become hostile. Promptly after joining Terminal Service One, Tsukasa is partnered with a beautiful Giftia named Isla. She is a Terminal Service veteran and considered the best in Giftia retrievals, contrary to her petite figure and placid nature. Time is fleeting though, and Tsukasa must come to terms with his feelings for Isla before her time is up. No matter how much someone desires it, nothing lasts forever.

After experiencing the numerous trials encountered on her journey, Reina has grown as a warrior. Determined to take part in the Queen's Blade tournament, she arrives at the capital city Gainos, where Queen Aldora awaits. There gathers a number of beautiful warriors who, like Reina, are there for the Queen's Blade. Amongst them is Reina's sister, Claudette, determined to restore the glory of House Vance; Tomoe and Shizuka, who are both fighting for their homeland of Hinomoto; Nanael who has been ordered to participate by the Archangel; and the subordinates of the Marshland Witch. All these beautiful fighters who gather in Gainos have been one objective, to win through the Queen's Blade, the tournament to select the strongest, most beautiful queen. Who would ascend to that glorious throne? That can only be determined via battle. (Source: AnimeNfo)

Queen's Blade OVA. Contains short stories from the lives of the warriors after the Queen's Blade competition.

Power corrupts, and it when it appears that the once noble Queen Claudette's ways have turned to oppression and heretical persecution, it's up to a new generation of warriors to step up to the plate armor to bear arms and bare their naked fury in open rebellion! The odds may seem unfairly stacked in favor of the Amazonian ranks of the queen, doubly supported by her power of writ and assassins. But the incredible wits and assets of the dazzling array of daring damsels willing to risk their gorgeous skins and put their lithesome bodies on line against her, might just expose a few unexpected weaknesses in the queen's support!
